the inverse poles: the crystal directions that lie along the specimen direction r, over the distinct equivalents of r under the specimen group; MATLAB’s inv(ori) * symmetrise(r)

Syntax

h = inversePoles(ori, zvector)

The crystal directions along z.

h = inversePoles(ori, zvector, antipodal=True)

As axes.

Description

They are what plotIPF draws for a list of orientations, which folds them into the fundamental sector of the crystal; here they are not folded. An axis and its antipode count once when antipodal is asked for, r is an axis, or -r is an equivalent of r.

Input

ori orientation, shaped (…)
r vector3d, one specimen direction

Keywords

keyword default description
antipodal False count an axis and its antipode once

Output

h vector3d in the crystal frame, shaped (…, m) over the m distinct equivalents of r
